Deeper water fish - effective number of species
Figure App.F.15.1.. A series of figures showing the equally-common species for kelp forest fishes (top), mobile bottom-associated invetebrates (middle) and deep water fishes (bottom) around the four Northern Channel Islands from 2005 - 2014.

Mean annual effective number of species for three taxonomic groups: kelp forest fishes (top), mobile demersal invertebrates (middle), and deeper water fishes (bottom). Shannon-Weiner diversity was converted to effective numbers of species, which allows for a more direct and intuitive comparison of community diversity over time. Kelp forest fish were surveyed across 86 shallow reef sites (3 to 16 meters depth) around the four northern Channel Islands from 2005 to 2014. Mobile invertebrates were surveyed across 63 shallow reef sites (3 to 16 meters depth) around the four northern Channel Islands from 1982 to 2016. Deep-water fish were surveyed at three reefs off the Channel Islands (Piggy Bank, Footprint, and Anacapa passage) at depths ranging from 40 to 407 meters in 1995 and annually between 1998 and 2011. Error bars indicate the 95 percent confidence interval in a given year. The horizontal line is the mean across sites over time.

Diversity of deep-sea corals at the eight study sites in southern California with the best ROV coverage, or research effort. The footprint (red) in the sanctuary ranks among the highest for biodiversity and abundance of deep-sea corals. Figure: Etnoyer et al. 2015Infaunal invertebrates - community composition

(Left) Infaunal invertebrate communities are characterized based on the proportion of a sediment sample with taxa that are sensitive (green, reference) as opposed to tolerant (red, high disturbance) of contaminant levels. (Right) In the most recent samples collected in 2013, ten of the 15 sites in Channel Islands National Marine Sanctuary had an infaunal community composition that was shifting to that which is more tolerant of degraded conditions (red) compared to the samples collected previously.

Figure App.F.15.2.. A figure showing the temperature preferences for kelp-forest fish species across the four Northern Channel Islands. Anacapa and Santa Cruz Islands show a more southern (warmer) collection of fish species while Santa Rosa and San Miguel Islands have a more northern (cooler) collection of fish species.
